This works fine, for a single figure. If multiple tikz graphs are included as svg, then their glyph definitions clash, and the second graph is rendered incorrectly in the notebook.

But it would be good if there was some option to include svg data in the notebook while ensuring that its definitions are kept private.
I suppose you should display it in an iframe, if you display the SVG with the isolated=true metadata,
IPython should do that for you automatically.
> On a related point, is there an easy way to export the .svg output of a cell to a file directly from within the notebook? I know that I could use nbconvert, manually hack the html, or find the temporary svg created by the magic, but I was hoping to find a more convenient way.
No, no easy way. For most content, drag-and drop from Chrome to my desktop seem to work here.
I was able to do it with SVG at some point, but today it refuses.
